Did she try to find any solutions when she calmed down? The porn is a solution he found to the issue that she doesn’t want to have sex as often as he does (which of course is a boundary she has every right to set), and she didn’t like that solution. Obviously she’s allowed to have feelings about all of this, and the lying wasn’t the best move, but her reaction also doesn’t seem like it provided a lot of space for compromise. Like I said, I don’t think she’s really an asshole per se because this can be a sensitive subject to deal with, but I also don’t think the fact that she had an emotional response automatically means he’s the only one who should be responsible for finding a way to work it out.
